Slide 1: Investor Day: Encoder Product Division
Investor Day Encoder Product Division 15th May 2014 Presented by Dr Jim Henshaw
Slide 2: Customer needs
Customer needs • Initial market was metrology, exploiting Renishaw’s contacts in the CMM market but later evolved into industrial automation. • Many manufacturing businesses are adopting industrial automation to: – Increase capacity and flexibility – Improve product consistency and quality – Reduce
Slide 3: Engineering solutions – what is a position encoder?
Engineering solutions – what is a position encoder? • A ‘position encoder’ converts position data into a ‘coded’ electrical signal. Consists essentially of 2 components: – Scale (a rule with accurate markings on it) – Readhead (a small device to read position information from the Scale) • The Scale
Slide 4: Engineering solutions – features of our encoders
Engineering solutions – features of our encoders • Non-contact – The readhead does not touch the scale – Position is sensed optically – No friction or wear • Hence: – Rugged and easy to install – Innovate to give competitive advantage
Slide 5: Engineering solutions – features of our encoders
Engineering solutions – features of our encoders • Linear – measure distance in a straight line…fixed, tracked… • Rotary – measure angular rotation about an axis…ring, disc… • Made in house – we own the processes • Typical performance: resolve to 10’s nm (below thousandth of hair’s breadth), tenths
Slide 6: Engineering solutions – features of our encoders
Engineering solutions – features of our encoders • Incremental and absolute measurement – Incremental reports relative position (how far have I moved?) – Conventional method…our early products – Absolute reports actual position (where am I?) – Newer…taking the innovative lead
Slide 7: Successful outcomes – encoder applications
Successful outcomes – encoder applications • Renishaw encoders are used in a wide variety of Manufacturing Processes Products industries and applications Electronics Metrology Semiconductor Machine tools • Large and growing market Flat panel display Aerospace with many opportunities but demand quali
Slide 8: Successful outcomes – Electronics manufacture
Successful outcomes – Electronics manufacture • Miniature electronic and optical components are positioned on boards and then bonded with glue or solder • Amicra Mikrotechnologie develops and manufactures Micro Assembly Cells designed for this purpose. • Amicra machines mount micro-components with a
Slide 9: Successful outcomes – Encoders in space!
Successful outcomes – Encoders in space! • Part of European Copernicus Earth observation programme • 1st of 5, Sentinel-1A launched 3 April ‘14 • 2 Renishaw rotary encoders on the Laser Communication Terminal for inter-satellite communication • Targets telescope at long range, typically 5000 km • Po
